IPC: H04L1/16
Filed: 2000-09-01
Abstract: PROBLEM TO BE SOLVED: To solve a problem of preventing wireless data transmission from deteriorating in transmission efficiency due to the fact that all frame data must be resent if even a signal error is found in the received frame data. SOLUTION: A data frame which has undergone error detection, error correction encoding, and bit interleave processing is divided into a prescribed number of blocks, and the blocks of data frame are stored in a block data split storage 6. A receiving end splits the received frame data as well as the block data split storage 6 and stored in a-block data storage synthesizer 16. When errors are detected after the frame data has been subjected to bit interleave processing and corrected for errors, an error pattern is estimated by an error system estimator 18, a block where errors occur is discriminated from others by a resending block discriminator 20, and a request to resend the data block is made. A sending end receiving the request to resend the data block extracts the designated data block from the block data split storage 6 to resend it to a receiving end.
